Fan-favorite creators Kurt Busiek and George Pérez craft a new era for Earth's Mightiest Heroes! The Avengers forge an uneasy alliance with the Thunderbolts to face Count Nefaria - but the true threat comes from the stars as Earth is declared a cosmic maximum-security prison for alien criminals!

But when the time-spanning Kang the Conqueror wages war on the present day - and wins - Captain America and a small band of rebels may be the world's only hope for freedom! Collecting AVENGERS (1998) #24-56 and #1 1/2, AVENGERS ANNUAL 2000-2001, THUNDERBOLTS (1997) #42-44, MAXIMUM SECURITY: DANGEROUS PLANET (2000), MAXIMUM SECURITY (2000) #1-3, and AVENGERS: THE ULTRON IMPERATIVE (2001).
